SYSTEM AND METHOD FOR LOCKING OBJECT BY USING INSTRUCTION SEQUENCE ON WHITE BOARD

摘要

PURPOSE: An object locking system and method is provided to give each object a locking function in a CANVAS(Creative And New technology virtual Application System), and give a session participant a locking right by the sequence of the transmitted locking request. CONSTITUTION: The system comprises a drawing tool(22), an object manager(23), a locking controller(24), a packet generator(25), a packet analyzer(27), and an instruction sequence controller(26). The drawing tool(22) generates the objects according a user request. The object manager(23) stores the generated objects, and manages the stored objects. The locking controller(24) determines the locking status of the stored objects. The packet generator(25) generates locking request packets on the locking request objects according to the determination result of the locking controller(24), and transmits the locking request packets to a white board of other session generator. The packet analyzer(27) analyzes the packets transmitted from the white board of other participants. The instruction sequence controller(26) classifies the locking request by the transmission time, and gives the participant the right to lock or release the objects.
